Block copolymers are being increasingly used for the fabrication of self-assembled photonic materials due to their intrinsic capability to form microstructures with characteristic scales of 10-100 nm. The confined self-assembly of block copolymers in emulsion droplets can give rise to photonic microparticles with a lamellar nanostructure showing bright, intense and tuneable structural colouration exploiting a simple supramolecular chemistry approach. Additionally, the project aim to combine structural colouration with broadband absorption to increase the colour contrast of the final pigments.
